RIK-210 is a star located north of Scorpius. It is known for its mysterious dimming events. [4] [2] The dips are observed with stable period of 5.667 days, but their triangular shape is inconsistent with the planetary eclipses. Instead, the diffuse cloud on synchronous orbit may be responsible. [3]
